Which medication should the nurse administer to a client with viral pneumonia?

In cases of viral pneumonia, the appropriate course of treatment often focuses on antiviral medications rather than antibiotics, as antibiotics are ineffective against viral infections. Among the choices provided, Oseltamivir stands out as the correct option because it is an antiviral medication specifically used to treat infections caused by influenza viruses. While Azithromycin is an antibiotic that may be used in cases of secondary bacterial infections that could complicate viral pneumonia, it does not directly target the underlying viral infection.

Viral pneumonia often requires supportive care and, in some cases, antiviral therapy if caused by influenza. Oseltamivir operates by inhibiting the replication of the influenza virus, thereby helping to reduce the severity and duration of the illness in affected individuals. Thus, for a client with viral pneumonia, Oseltamivir is the most appropriate medication among the options listed.
